Zuhair al Thubaiti was a candidate for the 9/11 plot. He has reportedly admitted membership in al Qaeda, stating "proudly" that he was among a select number of operatives who had the personal endorsement of Bin Ladin. He was not ultimately selected for the 9/11 attacks because the al Qaeda leadership considered him too high-strung and lacking the necessary temperament.
